Russians love raspberries and they adore sour cream. So when we started prepping for a special "Russian-fairytale-themed" birthday party, it did not take long to hit upon this creative pairing for a fitting gluten-free birthday cake. The party is geared mostly to six- and seven-year-olds, hence we are forming the batter into cupcakes and topping them with a beautiful, naturally pink raspberry frosting (frosting recipe courtesy of twopeasandtheirpod.com) as well. The sour cream in this recipe keeps the cake lusciously moist and provides just a hint of tanginess while the seedless raspberry filling and frosting bring surprising bursts of flavor, color, and just enough sweetness in all the right places.
Adorned with pretty liners and decorative gluten-free candies, these fanciful cakes would make a picturesque dessert not only for birthdays but for tea-time, baby and bridal showers, Valentine's Day or any romantic celebration. Ballerinas, babushkas, Bolsheviks, and boys named Boris all tell us they get homesick when they taste these delicious darlings, but you certainly don't have to be Russian to appreciate good cake. Na Zdorov'e!
Makes 12 standard-size cupcakes.
CUPCAKE INGREDIENTS
1/2 cup organic unsalted butter (one stick) softened until a knife can cut through it with no effort
1 cup sugar
3/4 cup organic sour cream
2 large organic eggs
2 tsps gluten-free vanilla extract
1/4 tsp ground pure vanilla, such as that produced by Ojio (optional)
1 1/2 cups Carol's all-purpose sorghum blend or similar flour blend*
1 tsp xanthan gum
1/2 tsp baking powder
1/2 tsp baking soda
1/2 tsp salt
*****
1/4 cup seedless raspberry jam
*To make four cups of Carol's Sorghum Blend, a great all-purpose gluten-free flour blend invented by Carol Fenster, combine the following:
1 1/2 cups gluten-free corn starch or potato starch (not potato flour!)
1 1/2 cups gluten-free sorghum flour
1 cup gluten-free tapioca flour
Whisk the three flours together well in a large bowl and then remove the 1 1/2 cups needed for the recipe. Reserve the excess flour for another use in an airtight container.
Other recommended flour substitutes include King Arthur's glutenfree multipurpose flour and Arrowhead Mills Gluten Free All-Purpose Baking Mix (just omit baking powder and baking soda if using the Arrowhead mix). If you choose another flour blend, please be sure it is a lighter, starchier blend rather than a high-protein blend (i.e., do not use any containing bean flours!) to preserve the fluffy texture of these cakes.
FROSTING INGREDIENTS
1 cup raspberries, preferably organic, fresh or frozen
2 cups powdered sugar, sifted and free of clumps
3/4 cup organic, unsalted butter (softened)
1/2 tsp gluten-free vanilla extract
******
12 gluten-free candies or other decorations (we used Surf Sweets' vegan Fruity Hearts in ours)
CUPCAKE METHOD
Preheat oven to 325 degrees Fahrenheit. Line a standard size, 12-holed cupcake pan with paper liners.
In a medium bowl, whisk together 1 1/2 cups of your chosen flour blend, xanthan gum, baking powder, baking soda and salt. Set aside.
Using a mixer, cream together the softened butter and sugar on medium speed. Add the eggs, one at a time, followed by the vanilla(s) and beat until incorporated. On low speed, slowly add half the flour mixture and then half the sour cream. Increase speed to fully combine and add in remaining flour and sour cream.
Beat on high speed for one minute and then stop the mixer to fully scrape down the sides of the bowl and dislodge any ingredients clumped in the beaters/paddle attachment. Beat one more minute or until the batter is smooth and webbed like frosting.
Fill each of the 12 cupcake liners approximately half-full (a cookie scoop works great for this task) and then spoon a small amount of jam (roughly 1/2 tsp) into the very center of the batter in each liner. Divide the remaining batter equally among the 12 cupcakes, being sure to cover the jam fully. Place the pan in the middle of the oven. Bake for 25-30 minutes. Cupcakes are done when the top springs back in response to a light touch. Remove from the oven and allow to cool in the pan for 5-10 minutes.
Carefully remove cupcakes from the pan (but do not remove liners) and allow them to finish cooling on a wire rack, for at least 90 minutes.
FROSTING METHOD
Pour the berries into a fine-mesh sieve or chinois placed over a medium bowl and mash the berries with the back of a metal spoon. If using frozen berries, it is important to defrost them first (you can simply place the berries in the sieve for several hours at room temperature and collect any consequent juices in the bowl and mash the berries when they have softened, or place the berries in a glass bowl and microwave briefly on medium power). Continue mashing until no additional liquid is extruded. You will have mostly seeds and some pulp in the sieve. Reserve the strained pulp (approximately 3 Tbsps) and set aside.
Sift powdered sugar and place it in a large mixing bowl. If you do not have a sifter or if your only sieve is now sticky and wet with raspberry juice, you can whisk the powdered sugar well, until no large clumps remain, in a separate bowl or you can throw throw the sugar in a blender for a few seconds. (Organic powdered sugar, for mysterious reasons, tends to be difficult to sift and overall very clumpy so you may want to use Domino or some other mainstream sugar for this recipe.) Add the softened butter and vanilla to the sifted sugar and mix on low speed to combine. Once most of the sugar is incorporated, you can begin to increase the speed gradually and then beat the frosting on high for at least one minute. Slowly add in the reserved raspberry liquid, a teaspoon or so at a time, until you reach your preferred frosting consistency. Be sure to stop the mixer and scrape down the sides of the bowl from time to time. Frost and decorate the fully-cooled cupcakes as desired. We used a piping bag fitted with a large star tip.
